To accommodate the changes in the new version of tourr that, for guided_tour(), users have to define a tibble record in the parent.frame() environment, else error occurs.
The main change: the **_tour(), e.g. grand_tour() will return a tour_path function. In the new tourr version, the returned data structure by tour_path is changed. In the past, one can query the interpolate directly from the returned object. However, in the new version, the interpolate object is beneath ingred.
